Online Monitoring Framework

Plans for prototyping and testing:

get 4x16 core box from CC 2pm today
turn RDC and rack circuits on today or tomorrow (Mark S)
install computer in Rack Room today or tomorrow, connect to network switch
install DAQ software (ET and cMsg)
create ET systems
create a fake event builder that feeds events into ET from a (large) simulated raw data file
run plugins off the ET system
view histograms with RootSpy
evaluate performance

Performance measurements:

ET throughput
monitoring processing rates
network and cpu loads
RootSpy performance
whatever else we can think of

Thus this will be a prototype of the DAQ/Monitoring system from the last event builder up to the event recorder.

I created plugins for the following detectors...these will comprise the foundation of the production online monitoring system:

BCAL
FCAL
ST
TOF
CDC
FDC
TAGM
TAGH
PSC
PS
TRIG
EVNT

They are independent and can be run in any combination. They book ROOT histograms in their own subdirectories and ROOTSpy will be used for remote histogram display. Currently I programmed energy/charge, time and occupancy histograms for the detectors supported by our simulation, the others (PSC, PS, TAGH, EVNT, TRIG) are skeletons. Dave suggests we run this package in the nightly build and regularly check the histograms.

I will fill in the empty plugins when the simulation is updated. I expect detector experts will expand the functionality of these plugins.

At the moment the plugins get information from HDDM files. Eventually they will get information from simulated raw event files once Dave completes the EVIO data source and raw data objects.
